Ukukhutshwa kwe-CO2 kubalulekile ekwandiseni umphumo we-greenhouse kunye neziphumo zotshintsho lwemozulu. Ngokophononongo olwenziweyo namhlanje kwi ingqungquthela yemozulu yaseMarrakech (COP22) lwenziwe ngabaphandi beprojekthi Iprojekthi yeCarbon Carbon, Ukukhutshwa kwe-CO2 kuhlala kuzinzile kunyaka wesithathu ngokulandelelana
Ngenxa yophuhliso lwamashishini, ukukhutshwa kwegesi yendlu eluhlaza kuye kwanda, kubandakanya ne-CO2 kakhulu. I-CO2 igcina ubushushu kwaye yiyo loo nto inyusa amaqondo obushushu aphakathi komhlaba. Uphononongo lwenziwe lwangqina ukuba enkosi ukunciphisa ukukhutshwa kweChina inyani yokuba bezinzile iminyaka emithathu.
Ukukhutshwa kwe CO2 jikelele kukhule kuphela 0,2% malunga neminye iminyaka. Ngunyaka wesithathu ukuba umhlaba ungakhange ulubone ukonyuka okungaka kokukhupha. Ngexesha leminyaka elishumi lokuqala le-2st century, ukukhutshwa kwe-CO3 kunyuke nge-XNUMX% ngonyaka.
Glen peters Ungomnye woososayensi abakhokele iprojekthi yokukhupha i-CO2 kwiatmosferi kwaye waqinisekisa ukuba sijamelene nemeko apho ukwanda kokukhutshwa kugqityiwe kuphuhliso loqoqosho. Kusekutsha kakhulu ukuba singasiqinisekisa esi sikhundla kuba ukukhutshwa kwehlabathi, nangona luzinzile, kusekho ngaphezulu komqobo oyimfuneko ukunciphisa iziphumo zotshintsho lwemozulu.
Ukusukela kutshintsho lwezezimboni, ukukhutshwa kwekhabhoni kunxibelelene nokukhula koqoqosho. Amazwe asaphuhlayo awakhupheli ikhabhoni eninzi emoyeni. Olu tyekelo lokudibanisa izinto ezikhutshwayo kunye nokukhula koqoqosho kufuneka lubhangiswe ukuze kuliwe notshintsho lwemozulu.
Ngokuka-Peters, uzinzo lokukhutshwa kwehlabathi kungenxa yokuwa kwabo e-China ukusukela ngo-2012 ngenxa yokukhula koqoqosho olusezantsi kunye ukusetyenziswa kwamalahle asezantsi. Izwekazi iAsia limele phantse Iipesenti ezingama-30 zokukhutshwa kwe CO2 kwihlabathi ke ngoko ukwanda okanye ukwehla kokusetyenziswa kwamalahle ngumba omisela ibhalansi yokukhutshwa komhlaba.
Kujongwe kwaye kulindelwe ukuba nge Isivumelwano saseParis, kakhulu I-USA ithanda iChina ukunciphisa ukukhutshwa kwehlabathi ngokunciphisa ukusetyenziswa kwamalahle kunye nokukhuthaza amandla ahlaziyekayo.
